How to Write a Demand Letter, From First Draft to Final Edit

What order should you write a demand letter in?

Write it backwards. Decide the ask first, then the facts that justify it, then the rule, and only then the opening. The reader sees the letter top to bottom, but you build it from the bottom up, so every paragraph serves the request.

1. The ask. One sentence: the dollar amount, or the specific action, such as a repair or a refund. If you cannot write it in one sentence, you are not ready to draft.
2. The deadline. A calendar date, such as 10 or 14 days after you send it, and the payment method.
3. The fact list. Five to ten dated sentences, each one something you can prove with a document or a message.
4. The basis. The contract clause, receipt or statute that turns those facts into an obligation.
5. The next step. What you will consider if they do not respond, stated without heat.
6. The opening. Now write the first sentence: who you are, what this is about and what you want.

If you would rather start from a fill-in structure, our demand letter template lays out the parts with sample wording. This guide is about the writing itself.

What tone should a demand letter have?

Calm, specific and businesslike. Write as if a judge will read it later, because one might. The courts' small claims guide asks plaintiffs to request payment before filing, and your letter can become the exhibit that shows you did.

The firm versions share three traits: a number, a date and a source. Adjectives drop out.

How do you write the facts and organize the proof?

Put one fact in each sentence, in date order, and tie each to a document. The reader should be able to check every sentence against an enclosure.

• Use dates, not "recently." "On June 4" can be checked. "A while ago" cannot.
• Name documents as exhibits. "Invoice 1189 (Exhibit A)" lets the reader find it in seconds.
• Quote short phrases. If the other side wrote "I'll pay you Friday," quote those words and the date of the text.
• Leave out feelings and history that do not affect what is owed.
• Send copies only. Keep originals, and keep a full set of what you sent.

How much law should a demand letter include?

Enough to show why the money is owed, and no more. One accurate citation beats five you have not read. In a simple contract dispute, the clause or the receipt can be the whole legal basis.

Some California claims do carry rules that change how you write and send the letter:

• Consumer claims under the CLRA. Before suing for damages, the consumer must give written notice of the specific violations, demand a correction, repair or replacement, and mail it certified or registered with a return receipt, no later than 30 days before filing (Civil Code section 1782).
• Bounced checks. A certified-mail demand naming section 1719, the check's amount and the service charge opens a 30-day window, after which treble damages of $100 to $1,500 can apply (Civil Code section 1719).
• Contracts without an interest rate. Interest runs at 10 percent per year after a breach (Civil Code section 3289(b)).

Cite a statute only after reading its current text on the Legislature's website, leginfo.legislature.ca.gov.

Demand letter editing checklist

Put the draft away for a few hours, then edit with these questions:

• Can someone who knows nothing about the dispute tell, from the first two sentences, what you want?
• Does the amount appear the same way every time it is mentioned?
• Is every fact dated and backed by an enclosure?
• Have you removed insults, guesses about motives and anything you would not want a judge to read?
• Is the deadline a calendar date with a payment method attached?
• Does the next step describe a lawful civil option, such as small claims, and nothing else?
• Is the recipient's legal name correct?
• Does it fit on one or two pages?

Example: one paragraph, before and after editing

Example (hypothetical): a homeowner in Long Beach paid a flooring installer a $2,600 deposit for a job that never started. Here is a first draft and the edited version.

The edit added four dates, an address, the amount twice and a payment method. It removed the review threat, the anger and the vague "a lot of money." If the installer was a contractor who required a state license, our guide to contractor refund demand letters covers rules specific to that trade.

Finishing touches before it goes out

Sign and date the letter, then mail it by a method that leaves a receipt. A bounced-check demand must go by certified mail, and a CLRA notice by certified or registered mail with a return receipt; for other letters, certified mail is a sensible default. An email copy gives the reader a fast way to answer.

If the reply opens a negotiation, Evidence Code section 1152 lets both sides talk about a compromise without the offer itself becoming proof that someone owed money.

When the draft keeps stalling

If you have rewritten the letter several times and still are not sure which facts matter, which rule applies or how to state the next step, that uncertainty is itself useful information. A lawyer can help when the claim involves a statute with notice rules, a large amount, a business with counsel, or a filing deadline that is getting close.
